TOOL-HOLDER.

Specification of Letters Patent.

Application filed April 16, 1908.

Patented July G, 1909.

Serial No. 427,371.

To all whom it may concern:

Be it known that I, ISRAEL LARsoN, a citizen of the United States,residing at Sandy, in the county of Salt Lake and State of Utah, haveinvented certain new and luseful Improvements in Tool-Holders, of whichthe following is a specification.

My invention relates to improvements in tool holders, and has for itsobject the provision of a combination tool holder which may be used fora number of different purposes and which will be thoroughly practicaland desirable.

Another object of my invention is the provision of a combination toolholder which may be used as a complete device of itself or may be usedin connection with a ratchet brace such as the one upon which patent wasgranted to me February 4, 1908, No. 878,404.

Another and further object4 of the invention is to provide a tool holderparticularly useful for boring, driving screws and work ing in small orcramped spaces, and which may be used simply as a straight handle tohold the tool or as a ratchet device to actuate the tool.

A final object of the invention is the provision of a device of thecharacter described which shall be of simple and durable constructionand which shall be eiiicient for the purposes intended.

With these and other objects in view my invention comprises a holderhaving jaws at one end for gripping the shank of a tool and a removablecap on the opposite end of the holder, a bearing point received in thecap, and means in the body of the holder for gripping and holding toolsof various sorts, the holder itself being adapted for connection withand to be used in connection with a ratchet brace.

The invention further consists of a combination tool holder embodyingcertain other novel features of construction, combi nation andarrangement of parts substantially as disclosed herein and asillustrated in the accompanying drawings, in which:

Figure 1, is a side elevation of my improved tool holder as in use as ascrew driver or like instrument. Fig. 2, is a'longitudinal sectionalview of the holder. Fig. 3, is a sectional view of the device asin usein connection with my improved ratchet brace (Patent No. 878,404)showing the application of the bearing point which is ordinarily carriedin the holder. Fig. 4 is the sectional detail showing the double endedpawl and its associated parts. Fig. 5 is a cross section of the line inF 2. Fig. 6 is a cross section of the line 66 in Fig. 9.. Fig. 7 is across section of the line 77 on Fig. 2.

In the drawings: The numeral 1, designates the main or body portion ofthe holder having an enlarged cylindrical portion 2, at one end to forma portion of the surface or circumference of the handle and from suchenlarged portion, this member is of reduced diameter to provide a shank3, which shank portion is longitudinally slotted as at 4, from theenlarged portion clear to the end of the shank. The shank has a smoothcylindrical portion 5, next to the enlarged portion thereof upon whichis rotatably held the sleeve 6, for operating the gripping jaws, thissleeve preferably having an octagonal outer surface as shown serving asa hand hold for rotating the sleeve. The shank is threaded from thecylindrical portion outward to the end thereof as at 7, and a sleeve 8,is secured upon the cylindrical portion of the stock or shank, by meansof the transversely arranged pin or screw 9, which sleeve is spaced fromand extends outward over the threaded portion of the stock. A flat slide10, is confined in the slot of the shank in rear of the transverse pin9, and the edges of the slide are threaded as at 11, to

be engaged by the internal screw threads 12,

on the operating sleeve 6, so that by rotating the said sleeve the slideis moved longitudinally in the slot of the shank. The forJ ward end ofthe slide is forked or bifur cated as at 13, to receive the inner endsof the clamping jaws 14, the pin 15, passing through the forked ends ofthe slide and the inner ends of the jaws to hold the parts together andcause the jaws to work in unison with the slide, and the jaws are heldnormally distended or open by means of the spring 16, which bears uponthe inner ends of the jaws. An internally threaded sleeve 17, is engagedupon the threaded portion of the shank, the end of the sleeve beingnormally in line with the end of the shank and the screw threads of thissleeve are terminated short of the end thereof as at 18. The clampingjaws have the beveled surfaces 19, to be engaged by the plain internalend portion 18, of the sleeve 17, and it will be apparent that byrotating the operating sleeve the clamping jaws are opened or closed asdesired to hold the proper tool such as a screw driver, gimlet, bit orvthe like.

In order to adapt the holder for service as a plain auger handle, asquare opening 2 is provided in the handle or enlarged portion of theshank and to clamp the tang of the auger when so inserted in saidsquared opening, a rearwardly projecting lug or eX- tension 21, iscarried by the slide which is notched as at 22, to engage and clamp thetang of the auger or other tool. The other main or body portion of theholder consists ot' the cylindrical member 23, having screw threadconnection 24, with the enlarged portion of the shank member, the lockscrew 25, serving to hold the respective members against accidentalrotation. The handle member is provided with a transverse cylindricalseat or recess 26, in which is rotatably held the ratchet 27, whichratchet is provided with a squared socket 2S, to receive the tang of abit or like tool. A double ended pawl 29, is pivoted at 30, and isshifted to engage either end of the ratchet tool socket by means of thetransversely arranged plungers or push buttons 3l, eX- tending outthrough opposite sides of the handle. rlhe central portion of theratchet tool socket is left plain in the form of an annular groove 32,so that the pawl will only engage the ratchet teeth at either end of thesocket holder. Thus a ratchet tool holder is provided for operating' atool in cramped spaces, the ratchet being operable for rotating ineither direction.

A hollow cap 33, is mounted on the end of the holder which serves as areceiver for the bearing point 34, the said bearing point bein'grotatably mounted on the screw threaded shank 35. This bearing point isused in the manner indicated in Fig. 3,V the screw threaded shank beingconnected to the bit stock 3G, as illustrated. The bearing point is heldin the cap by means of the spring 37, having the inturned end 38, toengage in the annular recess 39, in the shank of the bearing point. Thisspring is normally out of engagement with the bearing point but isdepressed into engagement with the point by means of the slide 40, whichhas a depending lug 4l, riding on the spring. The slide is actuated by athumb piece or button 42, held in the slot 43. Then the slide is pushedforward to lock the point in the cap, the end of the slide projects intothe seat 44,

in the end of the member 23, to lock the parts against unscrewing.

i It will thus be evident that the device may be used as in a plain T orauger handle, a ratchet tool holder, and by means of the clamping jawsthe holder may be used in connection with various tools. The holder isalso of importance for use in connection with my ratchet brace shown inmy Patent No. 878,404. Where my brace is being used in a cramped placeand it is impossible or impractical to use the crank arm of the brace,the crank arm is removed, the bearing point engaged on the end of thebit stock as in Fig. 3, and the internally threaded sleeve 1T, on theend of the shank is partially unserewed until it projects beyond the endof the shank and is then turned to make screw engagement with the arm ofthe bit holder as will be seen in the ligure referred to. lVhen sopartially unscrewed the protective .sleeve 8, prevents entrance of dustor any foreign matter to the screw threads on the shank. lnstead of the'conical bearing point, the bearing plate as shown in the patent may beused, or the cap 33, may be used as a handheld as indicated in dottedlines in Fig. 3.

From the foregoing description taken in Connection with the drawings,the many advantages and general usefulness of my improved tool holderwill be readily understood and appreciated, and it will be apparent thatI have produced a device of this character which fully andsatisfactorily accomplishes all the objects herein aimed at.

I claim:

l. In a tool holder, a body portion with enlarged portion at one end anda shank of reduced diameter longitudinally slotted from said enlargedportion to the end of the shank, a sleeve rotatively held upon theshank, gripping jaws, and a slide confined in the slot of the shank withits edge threaded and having threaded engagement with said sleeve, theforward end of said slide bifurcated to receive the inner ends of saidclamping aws.
